Multipolar Connector Shielding for Signal Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multipolar connectors experience signal interference between adjacent rows of terminals, particularly at high frequencies due to increased circuit density and signal applications.
Innovation Solution
Incorporating conductive shielding members between rows of inner terminals in a multipolar connector set, with each connector having multiple rows of terminals and insulating members, and optionally connecting outer terminals to ground potential for enhanced shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If terminals are arranged in multiple rows to increase the number of poles, then the connector can accommodate more signals without increasing longitudinal size, but signal interference occurs between adjacent rows of terminals
Solution Approach 1:
A conductive shielding member is introduced as an intermediary element positioned between adjacent rows of terminals. This shielding member acts as a mediator that blocks electromagnetic signals from crossing between rows, preventing interference while allowing the multi-row configuration to maintain high pole density without increasing longitudinal size.
Solution Approach 2:
The harmful electromagnetic field between terminal rows is extracted and redirected to ground through the conductive shielding member. By providing a dedicated path to ground, the interference signals are removed from the signal transmission path, allowing multiple rows to coexist without mutual interference.
2Object-affected harmful factors
If outer terminals are added for shielding, then electromagnetic wave interference is suppressed, but device complexity increases
Solution Approach 1:
The conductive shielding member serves multiple functions simultaneously: it provides electromagnetic shielding between terminal rows, acts as a ground reference, and can be integrated with the insulating housing structure. This multi-functionality reduces the need for separate shielding components, thereby limiting the increase in device complexity while achieving effective interference suppression.

AI summary
A multipolar connector set includes a first connector and a second connector fitted together. The first connector includes first inner terminals arranged in multiple rows and a first insulating member configured to hold the first inner terminals, and the second connector includes second inner terminals arranged in multiple rows and a second insulating member configured to hold the second inner terminals. The multipolar connector set further includes a conductive shielding member disposed between adjacent rows of the first or second inner terminals in a fitted state where the first connector and the second connector are fitted together, with the first inner terminals being in contact the second inner terminals.
